The number of knots in a particular type of wood can be modeled by a Poisson distribution with an average of 1.4 knots in 10 cub
Kamila [148]

Answer:

Probability that a 20- cubic foot block of wood has at most 1 knot P (X<=1) = 0.5918

Step-by-step explanation:

Average rate of knot= 1.4

Wavelength = 1.4

Geometric probability is given by:

P(X= K) = wavelength ^k × e^-wavelegth

P(X=0) = (1.4^0 × e^-1.4)/0!

P(X=0) = 1 × 0.2466 = 0.2466

P(X=1) = 1.4^1 × e^-1.4

P(X=1)= 1.4×0.2466= 0.3452

P(X<=1)= P(X=0) + P(X=1)

P(X<=1) = 0.2466 + 0.3452 = 0.5918

Hello.

From our initial value, the price is $21 for 1 hour. After this, each hour is $14 more. From this information, we can solve for how much parking would cost at 24 hours, or one day.

5, 77; 6, 91; 7, 105; 8, 119; 9, 133; 10, 147; 11, 161; 12, 175; 13, 189; 14, 203; 15, 217; 16, 231; 17, 245; 18, 259; 19, 273; 20, 287; 21, 301; 22, 315; 23, 329; 24, 343.

After 24 hours, the total price will be $343.

I hope this helps!

There are 10 computers and 5 students. How many ways are there for the students to sit at the computers if no computer has more
mestny [16]

Answer:

30,240 ways

Step-by-step explanation:

This question is bothered on permutation. Permutation has to do with arrangement.

If there are 10 computers and 5 students, the number of ways students will sit at the computers if no computer has more than one student can be expressed as;

10P5 = 10!/(10-5)!

10P5 = 10!/(5)!

10P5 = 10*9*8*7*6*5!/5!

10P5 = 10*9*8*7*6

10P5 = 30,240

Hence the number of ways is 30,240 ways
